An apparatus for mass synthesis of carbon nano-tubes having a propeller fan is provided to considerably reduce feeding amount of carbon source and delivery gas and to increase reaction yield in production of the nano-tubes by using the propeller fan to assist active contact between carbon source and catalyst metal and forced flow of reaction product. The apparatus comprises: a reactor(160) having inner space closed against external atmosphere and a heater; a catalyst feeding part(110) to supply catalyst to the reactor; a carbon source gas feeding part(120) to flow carbon source gas to the reactor; a hydrogen gas feeding part(125) to flow hydrogen gas to the reactor; an inert gas feeding part(130) to flow inert gas to the reactor; a gas exhausting part(140) to output the gas out of the reactor; a carbon nano-tube collector to collect carbon nano-tubes after synthesis in the reactor; and a propeller fan(180) that is mounted on the inner side of the reactor to generate forced flow in the inner space. The gas exhausting part further has a filter to screen the synthesized carbon nano-tubes and flows only gas out of the gas exhaust part. |
